Ethereum's Layer 2 ecosystem is booming, but fragmentation across rollups like Arbitrum, Optimism, and Base has left users and developers juggling multiple silos. Nomina, formerly Omni Network, is tackling this challenge with a protocol designed to unify Ethereum's L2s. But what is Nomina, and why did it rebrand?
What is Nomina and what problem does it solve?
Nomina is an interoperability protocol built as an Ethereum-native Layer 1. Its mission is to make Ethereum's fragmented rollup ecosystem feel like a single, unified network. Through chain abstraction, users can interact with dApps and assets across rollups without worrying about which chain they're on.
For developers, it offers EVM compatibility and a “build once, deploy everywhere” model, simplifying cross-rollup app creation.
How does Nomina secure the network?
Nomina uses a dual-staking model to secure its chain. This combines its native NOM token with restaked ETH via EigenLayer, giving it both its own security and Ethereum's economic guarantees. This hybrid system aims to ensure high reliability, censorship resistance, and protection against attacks.
Why did Omni Network rebrand to Nomina?
On September 5. 2025. Omni Labs announced the rebrand to Nomina. The new name reflects its broader vision of identity, trust, and accessibility in the DeFi world. Alongside the rebrand, the OMNI token migrated to NOM at a ratio of 1 OMNI to 75 NOM, with automatic migration for staked tokens and no deadline for holders to swap.
The project also saw key milestones, including exchange listings, ecosystem integrations with Gearbox Protocol and Cygnus Finance, and growing traction across Ethereum rollups.
Conclusion:
Nomina's rebrand signals more than just a name change—it's a clear commitment to solving Ethereum's rollup fragmentation. By offering chain abstraction, dual security, and seamless interoperability, Nomina could become the backbone of a unified Ethereum L2 experience. Its success will depend on whether developers and users embrace the shift toward a rollup-agnostic ecosystem.
